Materials Data on Ce3SiPt5 by Materials Project
Ce3Pt5Si crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Ce+3.33+ sites. In the first Ce+3.33+ site, Ce+3.33+ is bonded in a 11-coordinate geometry to ten Pt+1.20- and one Si4- atom. There are a spread of Ce–Pt bond distances ranging from 2.97–3.21 Å. The Ce–Si bond length is 3.20 Å. In the second Ce+3.33+ site, Ce+3.33+ is bonded in a 11-coordinate geometry to ten Pt+1.20- and one Si4- atom. There are a spread of Ce–Pt bond distances ranging from 2.92–3.41 Å. The Ce–Si bond length is 3.00 Å. There are two inequivalent Pt+1.20- sites. In the first Pt+1.20- site, Pt+1.20- is bonded in a 11-coordinate geometry to six Ce+3.33+, four Pt+1.20-, and one Si4- atom. There are a spread of Pt–Pt bond distances ranging from 2.88–3.02 Å. The Pt–Si bond length is 2.51 Å. In the second Pt+1.20- site, Pt+1.20- is bonded in a 2-coordinate geometry to six Ce+3.33+, four equivalent Pt+1.20-, and two equivalent Si4- atoms. Both Pt–Si bond lengths are 2.45 Å. Si4- is bonded in a 9-coordinate geometry to three Ce+3.33+ and six Pt+1.20- atoms.
